Description
Technical field
The present invention relates to liquid crystal technology field, particularly relate to a kind of display panels。
Background technology
Active-shutter 3D (ActiveShutter3D) Display Technique coordinates 3D shutter glasses to realize 3D by the liquid crystal display of high refresh rate and shows。Wherein the eyeglass of 3D shutter glasses substantially can control the two panels liquid crystal display screen of switch respectively, and this liquid crystal layer has black and white two states, and during non-power status, eyeglass is white and pellucidity, and during "on" position, eyeglass is changing to black。So can pass through a piece of liquid crystal display screen and receive the left eye picture signal of liquid crystal display, another sheet liquid crystal display screen receives the right eye picture signal of liquid crystal display, liquid crystal display launches synchronizing signal by sender unit simultaneously, makes to realize between the liquid crystal display screen switching of 3D shutter glasses and the right and left eyes picture switching of liquid crystal display accurate synchronization。
Liquid crystal molecule has the property that: if the direction of an electric field loading on liquid crystal layer two ends remains unchanged for a long time, then the characteristic of liquid crystal molecule will be destroyed, and namely cannot change in response to electric field rotate, thus forming different GTGs again。Therefore, it is necessary at regular intervals changing direction of an electric field to be liquid crystal molecule reversion, thus avoiding the characteristic of liquid crystal molecule to be destroyed。For this, industry has developed multiple driving method to realize the reversion (polarity inversion) of liquid crystal molecule, such as reversion (dotinversion) driving method, frame reversion (frameinversion) driving method, row reversion (columninversion) driving method and row reversion (rowinversion) driving method。
The general data signal transmitted on the data line, with common electric voltage Vcom as the reference voltage, it is possible to be divided into voltage be higher than this common electric voltage Vcom positive polarity data signal (+) with the voltage negative polarity data signal lower than this common electric voltage Vcom (-)。Positive polarity data signal refers to that its voltage is higher than common electric voltage Vcom, and negative polarity data signal refers to that its voltage is lower than common electric voltage Vcom。When same grey decision-making represents with positive polarity data signal and negative polarity data signal respectively, display effect is consistent in theory。
When active-shutter 3D liquid crystal display uses some inversion driving method to carry out picture pixel driving, the pixel polarity of liquid crystal display is as it is shown in figure 1,01 image frame to 04 image frame in Fig. 1 is continuous four frames display image frames。Owing to the odd-numbered frame picture of general liquid crystal display is used for showing left eye picture (or right eye picture), even frame picture is used for showing right eye picture (or left eye picture), picture signal such as liquid crystal display is left eye signal is high gray signal (such as white signal), right eye signal is low grayscale signal (such as black signal), then there will be the positive polarity pixel of the upper left of 01 picture in Fig. 1 (pixel of display positive polarity data signal) to be used for showing high gray signal, the negative polarity pixel (pixel of display negative polarity data signal) of the upper left of 02 picture is used for showing low grayscale signal, the positive polarity pixel of the upper left of 03 picture is used for again showing high gray signal。During due to low grayscale signal, it is no matter that positive polarity data signal or negative polarity data signal all can close to common electric voltage Vcom；And during high gray signal, it is no matter that positive polarity data signal or negative polarity data signal all can away from common electric voltage Vcom, the pixel so causing liquid crystal display is positive polarity pixel (display positive polarity data signal) in fact always or is negative polarity pixel (display negative polarity data signal) always, and liquid crystal display easily produces ghost phenomena (imagesticking)。
When active-shutter 3D liquid crystal display uses 2 frame point inversion driving methods to carry out picture pixel driving, the pixel polarity of liquid crystal display is as in figure 2 it is shown, 01 image frame to 04 image frame in Fig. 2 is continuous four frames display image frames。Picture signal such as liquid crystal display is left eye signal is high gray signal, right eye signal is low grayscale signal, then the positive polarity pixel of the upper left of 01 picture in Fig. 2 is used for showing high gray signal, the positive polarity pixel of the upper left of 02 picture is used for showing low grayscale signal, the negative tropism pixel of the upper left of 03 picture is used for showing high gray signal, and the negative tropism pixel of the upper left of 04 picture is used for showing low grayscale signal。Each pixel of such liquid crystal display had both shown the high gray signal of positive polarity, show yet the high gray signal of negative polarity, it is to avoid the generation of ghost phenomena。
But in the display process of this liquid crystal display, 02 picture and 04 picture of Fig. 2 are generally right eye picture, 01 picture and 03 picture of Fig. 2 are generally left eye picture, owing to 01 picture and 02 picture are the data signal of same polarity, when this data signal is displayed by liquid crystal display, need the electric charge in pixel is redistributed, it will cause that the brightness of the pixel after redistributing is higher, thus causing the brightness brightness higher than 01 picture of 02 picture；In like manner, the brightness of 04 picture is higher than the brightness of 03 picture, and namely the brightness of right eye picture is higher than the brightness of left eye picture。Liquid crystal display so can be caused easily to produce 3D ghost phenomena, affect the display quality of liquid crystal display。
